Zusammenfassung: | To provide a technique that allows a driver to recognize an overall image even when the position of an eye point changes.SOLUTION: A display device for a vehicle (10) allows a driver (Mn) seeing a display part (F) to recognize an arbitrary image by projecting the light emitted from a main body (20) on a display part (F) and controlling the light emitted from the main body (20) with a control part (11). The main body (20) comprises a first light path (Op1) and a second light path (Op2) that are adjacent to each other and have a different light path length to a display part (F) from each other, and a light blocking member (43) provided at the boundary between the first light path (Op1) and the second light path (Op2) and blocking the light. The control part (11) obtains information from an eye point position detection part (12) detecting the position of the eye point of the driver (Mn) and control the light emitted from the main body (20) based on the information.SELECTED DRAWING: Figure 1
【課題】視点の位置が変化しても像の全体を認識させることができる技術を提供すること。【解決手段】車両用表示装置(10)は、本体部(20)から出射された光を表示部(F)に投射させると共に、本体部(20)から出射される光を制御部(11)によって制御することにより、表示部(F)を見た運転者(Mn)に任意の像を認識させる。本体部(20)は、互いに隣接し、それぞれ表示部(F)までの光路長が異なる第1の光路(Op1)及び第2の光路(Op2)と、これらの第1の光路(Op1)及び第2の光路(Op2)の境界部に設けられ光を遮断する遮光部材(43)と、を備えている。制御部(11)は、運転者(Mn)の視点の位置を検知する視点位置検知部(12)からの情報を取得し、この情報に基づいて本体部(20)から出射される光を制御する。【選択図】図1 |
